I am a beginner. I apologize if these are especially stupid questions.

I tried installing Google Chrome. It didn't work. I tried both the 32 bit and 64 bit versions. I got messages about archive formats not being recognized, though I thought I had decompressed everything.

And now, as slh indicated, the package has been renamed "chromium" and the game is called "chromium-bsu", though "chromium-browser" still works as a transitional package. How many people thought they were installing a browser and ended up with an arcade-style space shooter game?
